The Indian Space Research Organization made the entire nation proud after it successfully launched India’s indigenous earth observation satellite — Hyper Spectral Imaging Satellite (HysIS) — aboard the PSLV C-43 from the Satish Dhawan Space Centre in Sriharikota.

Despite all the buzz around this earth imagery satellite, many people are still not sure as to what this space mission is all about and how the nation (and the world) will benefit from it. If you also find yourself in this category, then do not worry as we will try to explain everything that you are looking regarding HysIS:

Altitude and Orbit

HysIS will reportedly be launched at an altitude of 636 km from where it would be put into a polar sun synchronous orbit, which in turn will set it in motion along the axis that runs along the Earth’s geographic North and South Pole.

Physical Dimensions

The Hyper Spectral Imaging Satellite measures 2.158m x 1.386m x 1.121m, and weighs around 380 kg. It has been built around ISRO’s Indian Mini Satellite -2 (IMS-2) Bus and also comprises of a 64Ah Li-ion battery and a 730 watt power backup!

Objective of HysIS

HysIS’s mission is to study the earth’s surface within the visble, near infrared and shortwave infrared regions of the electromagnetic spectrum.

Uses and Functions

The indigenous satellite will come in handy for studying a number of phenomenons like climate change, atmospheric activity, earth’s magnetic field, etc. These observations could then be applied in numerous fields like water management, agriculture, forestry, coastal patterns, etc.

Duration of the Mission

HysIS’s lifespan has been ‘set’ to 5 years, which implies that the mission will come to an end in the year 2023.

More about PSLV

The Polar Satellite Launch Vehicle (PSLV) C-43, which consists of alternating solid and liquid stages, is 39.4 m in length.

Notably, the PSLV had carried out 39 consecutive successful missions until June 2017.

The vehicle has also been credited with launching the Chandrayaan-1 in 2008 and Mars Orbiter Spacecraft (Mangalyaan) in 2013.
